我写的日志机制不起作用。我用：
我对bean使用XML spring定义。 someModuleTarget是一个无法初始化的bean。我的应用程序中的一些bean被提供给org.springframework.aop.framework.autoproxy.BeanNameAutoProxyCreator，其中interceptorNames具有不同的事务传播（REQUIRE，NEW，ETC）
在应用程序部署期间出现问题，但仅当我在某些方法中使用新注释@TimeLog时才会出现问题。下面是一些代码。
注释记录机制：
@Aspect
public class TimeLogger {
@Around("execution(* *(..)) && @annotation(mypackage.TimeLog)")
public Object around(ProceedingJoinPoint point) throws Throwable {
Method method = MethodSignature.class.cast(point.getSignature()).getMethod();
//Why this returns TRUE only when I annotate both API and Impl of myAnnotatedComponent?
method.isAnnotationPresent(LogExecutionTime.class);
Object result = point.proceed();
LOG.info("some info");
return result;
}
}
@Retention(RetentionPolicy.RUNTIME)
@Target(ElementType.METHOD)
public @interface TimeLog {
LogLevels logLevel() default LogLevels.DEBUG;
}
Spring AOP配置：
<aop:aspectj-autoproxy/>
<bean id="execTimeLogger" class="mypackage2.TimeLogger">
</bean>
这是我得到的例外：

我发布了如何注入带注释的组件，作为一些注释的请求：
public class MyModuleImpl implements MyModuleApi {
private MyAnnotatedComponentApi myAnnotatedComponent;
//I also tried MyAnnotatedComponentImpl myAnnotatedComponent;
public MyAnnotatedComponentApi getMyAnnotatedComponent() {
return myAnnotatedComponent;
}
public void setMyAnnotatedComponent(MyAnnotatedComponentApi myAnnotatedComponent) {
this.myAnnotatedComponent = myAnnotatedComponent;
}
}
Spring bean定义：
<bean id="myModule" class="myPackage.MyModuleImpl" lazy-init="false">
<property name="myAnnotatedComponent" ref="myAnnotatedComponent"/>
<bean id="myAnnotatedComponent" class="myPackage.MyAnnotatedComponentImpl"
